01 - Preheat your heart-shaped waffle iron according to manufacturer's instructions until ready indicator light activates.
02 - In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until evenly distributed.
03 - In a separate bowl, beat the eggs thoroughly. Add the milk, melted butter, and vanilla extract. Whisk until fully incorporated and smooth.
04 - Pour the wet ingredients into the dry ingredients. Stir gently with a spatula or whisk until just combined—do not overmix. Small lumps in the batter are acceptable and will cook out.
05 - Lightly grease the preheated waffle iron with non-stick cooking spray or a small amount of melted butter using a pastry brush.
06 - Ladle or pour enough batter into the center of the waffle iron to cover approximately two-thirds of the cooking surface. Close the lid and cook for 3–5 minutes, or until golden brown and crispy.
07 - Carefully remove the cooked waffle using heat-safe tongs. Repeat the cooking process with the remaining batter until all waffles are prepared.
08 - Serve the heart-shaped waffles immediately while warm. Top with fresh strawberries, whipped cream, maple syrup, powdered sugar, or chocolate chips as desired.
